Let's divide 53164625 by 813
The aim is to understand the frequency of 813 in 53164625.

Step 1:
813 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 813

Step 2:
813 goes into 53 0 times with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 813

Let's proceed to step 3:
813 goes into 531 0 times with a remainder of 531.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 531 and we're left with 531.
Fetch the next digit (6) from the dividend, attach it to 531 and continue: 5316 / 813

Step 4:
813 goes into 5316 6 times with a remainder of 438.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4878 from 5316 and we're left with 438.
Grab the next digit (4) from the dividend, add it to 438, then carry on: 4384 / 813

Moving on to step 5:
When dividing 4384 by 813, we get 5 with a remainder of 319.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we subtract 4065 from 4384, we get 319.
Take the next digit (6) from the dividend and append it to 319, then repeat: 3196 / 813

Advancing to step 6:
3196 divided by 813 is 3 with a remainder of 757.
Write down 3 as next digit of the result. 
Result so far: 653.0
If we take 2439 away from 3196, we end up with 757.
Include the next digit (2) from the dividend after 757, then repeat: 7572 / 813

Advancing to step 7:
The number 813 fits into 7572 9 times, leaving a remainder of 255.
The next digit of our result is 9. 
Result so far: 6539.0
Subtract 7317 from 7572 to get 255.
Grab the next digit (5) from the dividend, add it to 255, then carry on: 2555 / 813

Step 8:
If we divide 2555 by 813, we get 3 and a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 65393.0
The remainder is 116 after subtracting 2439 from 2555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 9:
If we divide 1160 by 813, we get 1 and a remainder of 347.
Put 1 as the next digit of the answer. 
Result so far: 65393.1
Deduct 813 from 1160 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 10:
The number 813 fits into 3470 4 times, leaving a remainder of 218.
Record the quotient 4 as the next digit in the result. 
Result so far: 65393.14
The remainder is 218 after subtracting 3252 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 11:
The number 813 fits into 2180 2 times, leaving a remainder of 554.
The number 2 becomes the next digit in our result. 
Result so far: 65393.142
The remainder is 554 after subtracting 1626 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 12:
813 can be fit into 5540 6 times, resulting in a remainder of 662.
Write down 6 as next digit of the result. 
Result so far: 65393.1426
Subtracting 4878 from 5540 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 13:
When dividing 6620 by 813, we get 8 with a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 65393.14268
Subtract 6504 from 6620 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 14:
813 can be fit into 1160 1 times, resulting in a remainder of 347.
Use 1 as the next digit of our solution. 
Result so far: 65393.142681
Subtracting 813 from 1160 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 15:
If we divide 3470 by 813, we get 4 and a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 65393.1426814
The remainder is 218 after subtracting 3252 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 16:
If we divide 2180 by 813, we get 2 and a remainder of 554.
Record the quotient 2 as the next digit in the result. 
Result so far: 65393.14268142
If we subtract 1626 from 2180, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

The quotient of the division is 65393.14268142, and the remainder is 5.54e-07.
